Application filed November 12, 1917; Serial No. 201,614.

To all /witom t may concern.'

Be itknown that I, DAVID WRIGHT, a citizen of the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Drinking-Fountain Bubblers; and I do hereby decla-re the following to be a full, clear, and exact description of the invention, such as will enable` others skilled in the art to which it ap pertains to make and use the saine. y

My invention has for its object to provide an extremely simple and highly eflicient sanitary drinking fountain bubbler; and, to this end, it consists of the novel devices and combinations of devices hereinafter scribed and defined in the claims. K

In the accompanying drawings, which illustrate the invention, like characters indicate like parts throughout the several views.

Referring to the drawings,

Figurel is a view partly in side elevation and partly in central vertical section of a. drain bouwl supported from a wall and having the invention incorporated therein;

Fig. 2 is a plan view of the drinking fountain bubbler removed from the drain bowl and illustrated on an enlarged scale;

Fig. 3 is a horizontal section taken on the line 8-3 of Fig. 1, on an enlarged scale;

Fig. 4 is a detail view of the nozzle in vertical section taken on the line 4-4 of Fig. 2, on an enlarged scale; and

Fig. 5 is a. plan view illustrating a modification of the drinking fountain bubbler.

The numeral 6 indicates a drain bowl of porcelain or other suitable material, of any desired form, but,as shown,has an integrally formed bracket 7, which supports said drain bowl from a wall 8. A water supply 9, leading from a suitable supply under pressure, extends from the wall 8 through the bracket 7, with its delivery end terminating` in an upright position slightly above the bottom of the drain bowl 6. The iiow of water from the pipe 9 is controlled or en' tirely cut od by a hand valve 10.

Referring rst to the invention, as shown in Figs. 1 to 4, inclusive, the numeral 11 indicates a hollow ball-like head 4screwed onto the delivery end of the water pipe 9 and tapped at -its crown to receive and support in an upright position a nozzle 12, of novel construction.. The upper or delivery end of this nozzle 12 is formed oblique and the upper extremity thereof is curved toward the opposite side of said nozzle to afford a water deiiecting surface 13. It will also be noted that the delivery end of the nozzle 12 is also slightly contracted, as indicated at 14. Within the nozzle 12, are a plurality of circuinferentially spaced grooves 15, provided for preventing the water from setting up a vortex within said nozzle. The above described nozzle 12 will throw a stream of water X at an inclination of approximately iifteen degrees and, as shown, is preferably directed toward the front of the drain bowl 6.

As a guard to prevent a persons lips Z 1 from touching the nozzle 12, as diagram matically illustrated in Fig. 1 by broken lines, I provide an annular tubular member 16 that is axially alined with the nozzle 12 and spaced thereabove. This guard member 16 is supported from the head 11 by a plurality, (as shown four) of upwardly and outwardly curved tubular stems or arms 17. These stems 17 are relatively small in diameter, when compared with the guard member 16, and their lower ends are tapped into the head 11 and their upper ends are brazed or otherwise rigidly secured to said guard member. In the crown of the guard member 16, is an annular water discharge slip or orifice 18.

When the valve 10 is open, water entering the head 11 will find its way through the stems 17, guard members 16 and flow there--l over through the orifice 18. This overiow of water forms an annular curtain of water through and over which the stream X is thown. As this curtain of water from the orifice 18 flows both inward and outward.

over the guard members 16, a sort of a double walled curtain is formed.

When a person is drinking at the drinking fountain bubbler, he will naturally keep his` face and hands away from the water overflowing on the guard members 16, but, in case he should touch any part of the bubbler, the same will be thoroughly cleansed thereafter, for the reason that the water flows all over the guard members 16, stems 17 and head 11. It will thus be seen, that the improved drinking fountain bubbler can` not become contaminated with disease germs and dust and dirt cannot lodge thereon. By discharging the stream of water X at an in clination of approximately fifteen degrees, the same is thrown over and clear of the guard, thus preventing disease germs from IOO rcn'iaining on the streain, that might conie f'ron'i a personsl mouth while drinking and be transmitted to the neXt person drinking from the same bubbler.

In the modification shown in Fig. 5, the guard consists of four upwardly and outwardly curved tubular stems or arins 19, having their lower ends tapped in the head l1 and provided at their upper ends with small hollow ball-like heads 20.` In the crowns of these heads 20, are formed Water discharge shts or orifices 21, from which the Water will How over the guards 19-7-20, and` head 11.

Tha-t I claiin iszl. A drinking fountain bubbler comprising a water supply7 pipe having a nozzle, and a guard surrounding the nozzle and located thereabove, said guard' being connected to the water supply pipe and having at its crown a water discharge orifice through which water overflows onto the guard, said nozzle arranged to throw a stream of water conipleteb7 over and to one side of the guard.

2. A drinking fountain bubbler comprising a water supply pipe having an upright nozzle, and. a guard surrounding the nozzlel and located thereabove, said guard being connected to the Water supply pipe and having at its crown a water discharge orifice through which Water overflows onto the guard, the inner wall of the nozzle, at its upper extremity, being extended toward the opposite side thereof to afforda deflecting Copicsof thisvpatent may be obtained for five cents each, by addressing the fCommissioner of,Patents,
